Benefits of technology

The patent describes a receiver that can decode encoded data transmissions using multiple decoders that independently decode parts of the data using a decoding matrix. The decoders communicate with each other to coordinate the decoding process. This allows for faster and more efficient decoding of data in wireless communication networks. The technical effect of this invention is improved speed and accuracy in decoding data transmissions.

Problems solved by technology

While LDPC and other error correcting codes cannot guarantee perfect transmission, the probability of lost information can be made as small as desired.
LDPC was impractical to implement when developed in 1963.

Embodiment Construction

[0028]FIGS. 1 through 17B, discussed below, and the various embodiments used to describe the principles of the present disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged wireless communications device.

[0029]FIG. 1 illustrates an exemplary wireless network 100, which transmits ACK / NACK messages according to the principles of the present disclosure. In the illustrated embodiment, wireless network 100 includes base station (BS) 101, base station (BS) 102, base station (BS) 103, and other similar base stations (not shown). Base station 101 is in communication with base station 102 and base station 103. Base station 101 is also in communication with Internet 130 or a similar IP-based network (not shown).

[0030]Base station 102 provides wireless broadband access (via ba...

Abstract

A receiver capable of decoding encoded transmissions. The receiver includes a number of receive antennas for receiving data; a plurality of memory units for storing the received data; and a number of decoders configured to perform a Low Density Parity Check (LDPC) decoding operation. Each of the decoders further is configured to independently decode at least a portion of the received data using a portion of a decoding matrix. Each of the number of decoders coordinates the low density parity check decoding operation with other decoders. The decoders can use a parallel process, a pipeline process or a combination of a parallel and pipeline process.
